SAE 1016 is a low-carbon steel combining good machinability, good workability and good weldability. It is used for components case-hardened by carburizing. It is also used in the hot-rolled, annealed, normalized or cold-worked condition for a variety of construction and engineering applications. SAE 1016 has a relatively high manganese content (0.60-0.90%) for a low-carbon steel; this provides increased hardenability which is reflected in all uses and gives increased hardness and strength in the core of carburized parts and in uncarburized applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-58. Producer or source: Carbon steel mills.
